Fire extinguishing firefighting drone

ABSTRACT

The present invention relates to a fire extinguishing firefighting drone which, in case of a fire in a house, a structure, a building, or the like, can be rapidly introduced and extinguish a fire in an early stage of the fire, and can be remotely operated in an unmanned manner through connection with a central control system. The fire extinguishing firefighting drone includes a flight unit configured to include propeller units, a disaster prevention turret unit configured to spray a fire-extinguishing chemical, a plurality of movement units configured to move a body unit, and a disaster prevention means unit configured to be provided with items adapted to spray a fire-extinguishing chemical, to launch a fire-extinguishing bomb, or to save lives.

TECHNICAL FIELD

The present invention relates to a fire extinguishing firefighting drone, and more specifically to a fire extinguishing firefighting drone which, in case of a fire in a house, a structure, a building, or the like, can be rapidly introduced in an early stage and extinguish a fire, can freely perform ground movement and flight movement, and can be remotely operated in an unmanned manner through connection with a central control system.

BACKGROUND ART

Generally, firefighting helicopters are aircrafts which fly their bodies by means of lift force and propulsion force which are generated by flows of air passing over the surfaces of rotor blades when rotating the rotor blades by means of engines. Firefighting helicopters are being used for various purposes, such as transportation and movement, attacks, firefighting, etc.

In particular, firefighting helicopters are effectively used to extinguish fires at sites to which fire engines cannot move or fire hoses cannot be introduced, such as a forest fire, etc.

However, such firefighting helicopters have a disadvantage in that they can extinguish fires only outside houses or buildings, and have a problem in which they cannot substantially extinguish fires which break out inside buildings.

Recently, in order to perform rapid fire extinguishment, various firefighting robots and firefighting helicopters have been used at fire sites so as to approach staring locations of frames. In particular, with the development of unmanned aircraft technology, there is a tendency for unmanned aircrafts capable of performing assigned missions, i.e., an attack, reconnaissance, information relay, surveillance, etc, without pilots to be developed for the purpose of fire extinguishment and firefighting.

However, such unmanned aircrafts have a problem in that they cannot extinguish fires which break out inside buildings in their early stages.
